Batter's Eye

The batter's eye or batter's eye screen is a solid-colored, usually dark area beyond the center field wall of a baseball stadium, that is the visual backdrop directly in the line of sight of a baseball batter, while facing the pitcher and awaiting a pitch. This dark surface allows the batter to see the pitched ball against a sharply contrasted and uncluttered background. Its primary purpose is the safety of the batter. The use of a batter's background has been standard in baseball (as well as cricket) since at least the late 19th century. The batter's eye performs the same role at a baseball venue as the sightscreen does at a cricket venue, except that a cricket sightscreen is usually white in order to contrast with the dark red cricket ball. Alternatively a black screen is used to contrast the white Kookaburra Limited Overs cricket ball.
